![]() ![]() Here A2 is greater in magnitude compare to A1. Often in ASK modulation, binary-1 is represented by carrier with amplitude-A2 and binary-0 is represented by carrier with amplitude-A1. no carrier).ĪSK modulation can be represented by following equation: As shown in the figure, binary 1 will be represented by carrier signal with some amplitude while binary 0 will be represented by carrier of zero amplitude(i.e. ![]() The figure depicts operation of ASK modulation. In this technique, amplitude of the RF carrier is varied in accordance with baseband digital input signal. The short form of Amplitude Shift Keying is referred as ASK. HDMI Encoder Modulator, 16in1 Digital Headend, HD RF Modulator at Input binary data is referred as modulating signal and output is referred as modulated signal. Unlike Analog modulation, here input is in digital binary form. All these are digital modulation techniques. PSK provides difference between ASK, FSK, PSK modulation types.
